Japanese Macaque

Japanese Macaque






Mixed forest

Latin Name

Macaca fuscata

IUCN conservation status

They're the most northern primate species in the world! In winter, their coat's thickness increases to allow them to withstand the cold!

A Varied Diet Depending on the Season and Availability.

Being omnivores, Japanese macaques prefer fruit, berries and nuts. They also eat mushrooms, insects, snails, crustaceans and bird eggs when these are available. In winter, they survive mainly on fat reserves and feed on bark and buds.

Data Covering more than 50 Years

They're probably the most studied primate species in the world. Among other observations, researchers watched a young macaque wash sand-covered pieces of sweet potatoes that the scientists had thrown on the beach to lure them out of the forest. This behaviour was then adopted by the other members of the group.

A Hierarchy Based on Females Rank

They live in groups of 20 to 100 individuals, in a matrilineal organization, around a dominant female. They're all related and never leave the group in which they were born. The males gravitate around the group and their hierarchical system is much more subject to change.

Protected, they're still Sensitive to the Deterioration of their Habitat

Confined to certain Japanese islands, Japanese macaque populations have enjoyed a high level of protection, especially since they were declared a " Natural Treasure of the Nations " in 1970. But deforestation of their habitat, and occasional conflicts with humans, threaten their long-term survival.
